Orbital myositis is an idiopathic inflammation of the extraoccular muscles. It is often included under the broad description of orbital pseudotumor. It is commonly a unilateral affection.
We report one case of bilateral orbital myositis in a 45-year-old woman. The first symptoms were diplopia and acute bilateral orbital pain exacerbated by eye movements. Physical examination especially neurological was normal. Serum creatine kinase and biological thyroid function were normal. CT scan found a bilateral enlargement of rectus oculi medialis and lateralis. Clinical improvement was obtained a few days after oral corticosteroid treatment with remission of all signs.
Orbital myositis is a rare entity. 90-95p.cent of cases are unilateral. Bilateral forms are exceptional and in this case require search for specific etiologies particularly thyroid ophthalmopathy. There is controversy concerning treatment options but corticosteroids are still the most common first choice therapy with good outcome.
眼眶肌炎是眼外肌的特发性炎症。它常被纳入眼眶假瘤这一宽泛的描述范畴。通常为单侧发病。
我们报告一例45岁女性双侧眼眶肌炎病例。首发症状为复视和双眼运动时加剧的急性双侧眼眶疼痛。体格检查尤其是神经系统检查正常。血清肌酸激酶和甲状腺功能指标正常。CT扫描发现双侧内直肌和外直肌增粗。口服皮质类固醇治疗数天后临床症状改善，所有体征均缓解。
眼眶肌炎是一种罕见疾病。90% - 95%的病例为单侧发病。双侧发病形式罕见，在此类病例中需要寻找特定病因，尤其是甲状腺眼病。关于治疗方案存在争议，但皮质类固醇仍是最常用的首选治疗方法，疗效良好。
